To all whomit may concern: 7 7

Be it known that we, lVIARSTON M N TIIORPE, of No. 1 Hans Tavsensgade, Copen hagen, Denmark, civil engineer, and ARTHUR" INGEMA N -HANSEN, of No. 16 Strandparksvej, Hellerup, Copenhagen, Denmark, civil engineer, have invented certain new and useful Improvements in Apparatus for:

Automatically Indicating the Position of Signals on Locomotives; and we do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw-f ings, and to letters or figures of reference marked thereon, whichform a part of this" specification. s

The present invention relates to an apparatus of the kind which automatically indicates on the locomotive itself the position of the signals along the railway track, and which consists of an adjustable member arranged alongside the track and capable of acting upon arms movably attached to the locomotive.

The invention is a form of construction of an apparatus of the said kind, by means of which theireliability in working is greatly increased and the possibility of the apparatus getting out of order is minimized. The adjustable member consists of a rotatable vertical shaft carrying a chain-wheel capable of being moved in either direction by means of a chain. The arms on the locomotive move when actuated by the adjustable member, in between the branches of an elastic fork, which fork is inserted as a kind of interrupter in an electric circuit on the locomotive. The said arms constitute themselves contact pieces and close the circuit direct, without any intermediate member when they are moved within the fork. It will by means of the said apparatus be possible in all kinds Of weather to easily observe the signals on the locomotive itself.

On the accompanying drawing the invention is shown diagrammatically in three forms of construction.

Figure 1 shows a form of construction of the apparatus in front view arranged to the right of the track. Fig. 2 the same apparatus seen from above. Fig. 3 a sectional I View of avertica-l arm and fork mounted on the locomotive. Fig. 4 a horizontal section through the arm and fork shown in Fig. 3. ig. 5 shows the second form' of construct on of the vertical arm and fork on the locomotive engagingwith the Operating shaft I on the track. Fig.6 shows the third form of construction in front view.

1 indicatesthe sleepers, 2 the rails, 3 the .locomotive and 4; the wheels. To the right of the rails a verticalshaft 5 is arranged, said shaft beingaprovideduwith a sprocket wheel 6 and two horizontal branches 7 and 8 placed right angles to each other and at different heights on the shaft. The shaft 5 can turn in a bearing 20, which can be 1 fixed for instance to a sleeper 1. The shaft 5 might also be placed between the rails. l The sprocket wheel 6 engages with a chain, not shown on the drawing, said chain co-acting with the operating gear'to the signal mast in such a manner that the shaft 5 as well as the signal are operated by the same manipulation from the signal station.

In the position of branch 7 as shown in Figs. 1 and 2 the said branch strikes the vertical arm 9 pivotally arranged on a shaft 10 mounted on a plate 24: fixed to the locomotive. The arm 9 is arranged to slide with some friction in an elastic fork 11, Figs..1, 3 and 4, which on the inner side is coated with apartly insulating and partly conducting material respectively 12 and 13 Figs. 3 and 4. The arm 9 consists of conductive material. The parts 13 are connected each with a conductor 14 in which is inserted a current source with a lamp. WVhen the arm is in position shown in Figs. 3 and 4 the current is broken, and the lamp does not burn. WVhen the arm 9 strikes the branch 7 and is turned to the left, see Figs. 3 and 4c, the current is closed and the lamp burns until the arm 9 is again turned back by hand. If, on the other hand the shaft 5 is turned 90 from the position shown in Fig. 1, so that the branch 8 now points to the left, it will strike another longer arm 15 which in appearance, form and fixing corresponds exactly to the arm 9, and another circuit is closed whereby a lamp of another color is lighted. The position of the signals is thus transmitted through the arms 7 and 8 to the locomotive itself.

In the arrangement shown in Fig. 5, the locomotive is only fitted with one arm 16.

The fork, corresponding to the fork 11 in ing the contact 18. Each of these contacts is, as described in the above form of construction, inserted in a corresponding electric circuit on the locomotive.

I11 the form of construction shown in Fig. 6 the shaft 5 has but one horizontal branch 7, the shaft 5 being placed mid-ways between the vertical arms of equal length 15 and 9. According to the position of the shaft 5 the branch 7 will strike either the arm 15 as shown in Fig. 6, or the arm 9 when the shaft 5 is turned 180, the branch 7 pointing to the right. Otherwise the apparatus acts as the one shown'in Figs. 1 and 2.

WVe claim 1. In a signal indicating means, the combination with two independent swinging contacts carried by a locomotive, of a trip device comprising a vertical shaft, means to rotate the latter, and means carried by the shaft to alternately project into the paths of said contacts.

2. In a signal indicating means, the combination with two independent contacts carried by a locomotive, of a trip device comprising a vertical shaft mounted between the paths of said contacts, and having a horizontal arm adapted to alternately project into the paths of said contacts, and means to rotate the shaft to swing the arm into said paths.

In testimony that we claim the foregoing as our invention, we have signed our names in presence of two subscribing Witnesses.
